Abstract

OBJECTIVE: To develop prototypes of tubular medical devices using 3D printing of polymers, evaluating their technical-scientific feasibility and potential application in the Brazilian Unified Health System (SUS), with a view to contributing to the incorporation of this technology within the scope of Brazilian public health. METHOD: Experimental study using commercial polymers (TPU Flex, Nylon, Tritan, PLA Flex and ABS) processed by FDM printing. The prototypes were developed using CAD modeling and characterized by Scanning Electron Microscopy (SEM), with comparative parameters established from commercial JOTEC devices. Results: The TPU flex 98A prototypes showed the best performance, especially in terms of flexibility and surface homogeneity. Conclusion: 3D printing of commercial polymers represents a technologically viable alternative for the production of personalized medical devices, with potential impact on Brazilian public health through technological independence.
